  The CPU 11 executes various processes in accordance with programs stored in the ROM 12 and programs loaded from the storage unit 18 into the RAM 13. Further, as will be described later, the CPU 11 generates information indicating a user's tendency based on device information and operation history information acquired from other devices, and controls various operations using this information. The information indicating the user's tendency is obtained by extracting information indicating the user's tendency and characteristics from the device information and the operation history information. For example, in the case of a program viewing history of a television device, the news program is viewed in the morning. It is often preference information that many sports programs are viewed at night. Thereby, for example, a keyword related to preference information can be extracted, and a search can be performed using the keyword. For example, the information displayed on the display screen of the output unit 17 can be changed according to the user's preference.

  The RAM 13 appropriately stores data necessary for the CPU 11 to execute various processes. The RAM 13 stores and updates its own operation history information generated by the CPU 11.

  The CPU 11, ROM 12, and RAM 13 are connected to each other via a bus 14. An input / output interface 15 is connected to the bus 14. An input unit 16, an output unit 17, a storage unit 18, and a communication unit 19 are connected to the input / output interface 15.

  The input unit 16 includes a keyboard, a mouse, and the like, and inputs instructions from the user.

  The output unit 17 includes a CRT, LCD, speaker, etc., and provides information to the user.

  The storage unit 18 is configured by an HDD (Hard Disk Drive) or the like, and exchanges data with the CPU 11 to save and erase information. For example, device information and operation history information obtained through the communication unit 19 are stored and read out to the CPU 11 as necessary.

  The communication unit 19 includes a modem, a terminal adapter, and the like, and performs communication processing via the Internet 2. In addition, the data provided from the CPU 11 is transmitted, and the data received from the communication partner is output to the CPU 11, the RAM 13, the storage unit 18, and the like.

Further, as will be described later, device information and operation history information are acquired from other devices, the information is reflected in the own operation, and user operations are assisted.

  FIG. 4 is a block diagram illustrating a configuration of the television device 2 in the above-described operation control system. The television device 2 includes a tuner 21, a demodulator 22, a separator 23, a decoder 24, a RAM 25, a MUX 26, an audio output unit 27, a composer 28, a display unit 29, and a graphic processing controller 30. A U / I control unit 31, a communication unit 32, a CPU 33, a RAM 34, a ROM 35, a storage unit 36, and a bus 37.

  Broadcast waves received by the antenna 4 are supplied to the tuner 21. Here, the broadcast wave is based on a predetermined format, and this broadcast wave may include, for example, EPG (Electronic Program Guide) data. The broadcast wave may be distinguished from satellite broadcast wave, terrestrial wave, wired or wireless, digital broadcast wave, or analog broadcast wave.

  The tuner 21 performs tuning of a broadcast wave of a predetermined channel, that is, tuning, based on the control of the CPU 33, and outputs received data to the demodulator 22. Note that the configuration of the tuner 21 can be changed or expanded as appropriate depending on whether the broadcast wave to be transmitted is analog or digital.

  The demodulator 22 demodulates the digitally modulated received data and outputs the demodulated data to the separator 33. The digital data received by the tuner 21 and demodulated by the demodulator 22 is, for example, a transport in which AV data compressed by the MPEG2 system and broadcast data are multiplexed when the received broadcast is a digital satellite broadcast. It is a stream. The former AV data is video data and audio data constituting the broadcast content body, and the latter broadcast data includes content description data (for example, EPG data) attached to the broadcast content body.

  The separation unit 23 separates content description data associated with content such as EPG data and AV data from the demodulated reception data. AV data is output to the decoder 24. The content description data is input to the CPU 33 via the bus 37, and necessary keywords are extracted and stored in the storage unit 36.

  The decoder 24 compresses the AV data supplied from the separation unit 23 into the compressed video data and the compressed data according to the control signal input from the CPU 33 when the user instructs the real-time output of the received content. Is separated into audio data. The separated audio data is decoded by PCM (Pulse Code Modulation) and then output to an audio output unit 27 including a speaker or the like via a mixer (MUX) 26. The separated video data is expanded and then supplied to the composer 28.

  A RAM (Random Access Memory) 25 can store the work data performed by the decoder 24.

  The composer 28 synthesizes the video data input from the decoder 24 and the image data input from the graphic processing controller 30 as necessary, and outputs the result to the display unit 29 including a display. The display unit 29 displays (reproduces) the video signal supplied from the composer 28.

  The graphic processing controller 30 is a dedicated controller that generates image data, and has a high-definition drawing function equivalent to, for example, SVGA (Super Video Graphic Array) or XGA (extended Graphic Array). For example, the graphic processing controller 30 generates a GUI (Graphical User Interface) operation screen on which a user can input various settings.

  The U / I (user interface) control unit 31 is a module that processes an input operation from a user. For example, when a user operates a remote commander (not shown) including operation buttons or switches. The operation signal (IR signal) emitted from the infrared light emitting unit (not shown) is received by the light receiving unit and output to the CPU 33 via the bus 37.

  The communication unit 32 controls wired communication using a telephone line or a cable. For example, by communicating with a server system (not shown) via the communication unit 32, broadcast contents or EPG data can be exchanged. Also, the broadcast content input to the communication unit 32 can be input to the separation unit 23 via the bus 37 and processed in the same manner as the broadcast data input via the tuner 21 and the demodulation unit 22.

  Further, by communicating with an external device via the communication unit 32, device information and operation history information of other devices can be input / output. Device information and operation history information input to the communication unit 32 are input to the CPU 33 via the bus 37, and, for example, keywords relating to preference information are extracted. The extracted keywords are accumulated in the storage unit 36 via the bus 37.

  The CPU 33 is a main controller that controls the overall operation of the television apparatus 2 and executes various applications on a platform provided by an operating system (OS). For example, by controlling the tuner 21, demodulator 22, separator 23, decoder 24, storage unit 36, etc. based on the operation signal input from the remote commander via the U / I controller 31 and the bus 37. Execute content playback and the like. Further, as will be described later, the CPU 33 generates preference information indicating the user's tendency from the device information and the operation history information acquired from other devices, and controls various operations using the preference information.

  A RAM (Random Access Memory) 34 is a writable volatile memory used for loading an execution program of the CPU 33 and writing work data of the execution program. A ROM (Read Only Memory) 35 is a read only memory for storing a self-diagnosis / initialization program executed when the power is turned on, a control code for hardware operation, and the like.

  The storage unit 36 is a storage device such as an HDD (Hard Disk Drive) or a memory card that can store programs and data in a file format of a predetermined format and can be randomly accessed. The storage unit 36 stores input content description data. The content description data is read into the CPU 33 via the bus 37 as necessary. As a result, the CPU 33 executes predetermined processing according to a predetermined application, for example, reads out a keyword related to the content being viewed from the storage unit 36 and supplies it to the graphic processing controller 30 to generate a screen as described later. can do. In addition, device information and operation history information of other devices are stored in the storage unit 36 and can be reflected in the operation of the device itself as will be described later.

  The television apparatus 2 having such a configuration provides information to the user by receiving broadcast waves and displaying content on the display unit 29, for example. Further, as will be described later, device information and operation history information are acquired from other devices, the information is reflected in the own operation, and user operations are assisted. For example, the screen display method is changed based on device information acquired from other devices as described later.

  Next, the operation changing process in the information processing apparatus 1 and the television apparatus 2 described above will be described with reference to the flowchart shown in FIG.

  First, the electronic apparatus such as the information processing apparatus 1 or the television apparatus 2 determines whether or not other communicable apparatuses can be reflected in the operation of the apparatus (step S11). For example, whether or not device information and operation history information can be output from an electronic device to another device is transmitted, and if a reply is not received from another device within a certain period, it is determined that acquisition is impossible, and within a certain period When a reply is received from another device, it is determined that it can be acquired. If it is determined in step S11 that device information and operation history information can be acquired from another device, the process proceeds to step S12. If it is determined that acquisition is impossible, the process proceeds to step S17, the previous operation is performed, and the process ends.

  In step S12, the electronic device requests device information and operation history information from other devices. Then, device information and operation history information are received from other devices (step S13), and the operation to be changed is determined from the information (step S14). For example, when the information processing apparatus 1 receives device information and operation history information from the television apparatus 2, a keyword related to preference information such as “sports” is extracted from program viewing history information included in the operation history information, and the keyword is extracted. Decide to use for narrowing down search sites. That is, a preference such as a user's tendency is analyzed from the device information and the operation history information, and the operation is determined based on the preference analysis result.

  In step S15, the electronic device determines whether or not to change the operation determined in step S14. This determination is made, for example, according to the driving time of the device included in the operation history information. Thereby, for example, when device information or operation history information of the information processing device 1 is acquired, a screen similar to the setting screen of the information processing device 1 is displayed, and a detailed display according to the use frequency of the information processing device 1 By performing the above, it becomes a device having the best operability for the user. Further, for example, a selection screen as to whether or not to change the operation may be displayed on the display screen of the output unit 17 and may be performed by a user operation from the input unit 16.

  If it is determined in step S15 that the electronic device is to change the operation, the process proceeds to step S16, the operation is changed, and the process ends. If it is determined in step S15 that the electronic device does not change the operation now, the process proceeds to step S17, the operation is the same as before, and the process is terminated.

  In addition, it is preferable that the electronic device that transmits the device information and the operation history information and the electronic device that receives the device information and the operation history information are used by the same user. Identification information may be added. Only when the personal identification information matches, the device information and the operation history information are transmitted or received, thereby ensuring the protection of the personal information and the identity of the user who uses each electronic device.

  Next, an example of an operation changed by the above-described operation changing method will be described.

  FIG. 6 shows a display example when the input is switched by the input switching button in the television apparatus 2. This input switching is preset so that the display is switched in the order of “TV1ch”, “video1”, and “video2” as shown in FIG. 6A every time the user presses the input switch button on the remote commander. It is a thing. Here, when the device information can be acquired, the television device 2 determines the operation to be changed from, for example, the operation change list stored in the ROM 35 according to the type or category included in the acquired device information. To do. For example, in the display example by input switching shown in FIG. 6B, the device information of the information processing apparatus 1 is acquired, the keyword “information processing apparatus” is extracted from the device information, and the input switching operation according to the keyword is performed. If changes are allowed. In this case, the television apparatus 2 performs display switching control in the order of “TV1ch”, “video1”, “video2”, and “Memory card”. That is, since the device information includes a keyword related to the preference information “information processing apparatus”, the information is switched in order by the input switching button, and “memory card” is added to the preset input destination. For example, a list of representative screens of contents stored in the memory card of the storage unit 36 is displayed on the display screen of “Memory card” and can be selected by the user.

  Moreover, it is preferable that the television apparatus 2 acquires the operation history information of the information processing apparatus 1 together with the device information. Accordingly, for example, it is possible to determine whether or not to change the operation according to the driving time of the information processing apparatus 1 included in the operation history information, and to automatically change the operation.

  FIG. 7 shows a display example of a program guide in the television apparatus 2. For example, as shown in FIG. 7A, the television device 2 creates a program table of “XXTV”, “ABTV”, and “CBTV”. The program guide is created based on content description data accompanying the content, such as EPG data. Here, when the device information can be acquired, the television device 2 performs, for example, an operation to change from the operation change list stored in the ROM 35 in accordance with the type or category information included in the acquired device information. decide. The display example of the program guide shown in FIG. 7B is a case where the device information of the information processing apparatus 1 is acquired and the change of the display operation of the program guide is permitted. ”,“ ABTV ”,“ CBTV ”program guides, and“ Memory card ”. In this program guide, for example, by dragging the program “XXTV” to “Memory card”, it is possible to instruct the memory card to make a recording reservation for the program.

  Further, FIG. 8A is a display example of the program table of “XXTV”, “ABTV”, and “CBTV” as in FIG. 7A. FIG. 8B is an example in which a program of a certain category is highlighted based on the operation history information of the information processing apparatus 1 in the program table shown in FIG. In this case, the television apparatus 2 extracts, for example, a program category keyword from the Web history information included in the operation history information, and highlights the program of the category. For example, performer information may be extracted from Web history information instead of a program category keyword, and a program in which the performer appears may be highlighted.

  FIG. 9 shows an example when the information processing apparatus 1 performs a search by connecting to a search site. As shown in FIG. 9A, the information processing apparatus 1 normally accesses the search site, inputs a keyword in the search keyword input field 92 in the screen of the search page 91, and the user clicks the search button 93. Thus, the keyword is transmitted to the search site. Then, the search site searches for a keyword from the database in the site and transmits the result to the information processing apparatus 1.

  Here, the case where the program viewing history information of the television device 2 is acquired and the program viewing history information is reflected in the search will be described with reference to the flowchart shown in FIG. As shown in FIG. 9B, the user inputs a search keyword in the search keyword input field 95 in the screen of the search page 94 (step S21). The information processing device 1 extracts a history keyword from the program viewing history information included in the operation history information of the television device 2 (step S22). For example, the history keyword may be described most frequently in content description data associated with content that the user has recently viewed.

  In step S23, the information processing apparatus 1 adds the history keyword extracted in step S22 to the search keyword. In the example of FIG. 9B, history keywords “health” and “food” are added to “TV” input in the search keyword field. In step S23, when the user clicks the search button 96, the search keyword to which the history keyword is added is transmitted to the search site (step 24), and the search result is displayed on the display (step S25).

  Thus, for example, by using the program viewing history information of the television apparatus 2, the information processing apparatus 1 can perform a search reflecting the user's preference.

  In addition, as illustrated in FIG. 11, the information processing apparatus 1 may narrow down search results of a search site using a history keyword. In this case, as shown in the flowchart of FIG. 12, first, the user inputs a search keyword in the search keyword input field 112 in the screen of the search page 111 (step S31). When the user clicks the search button 113, the information processing apparatus 1 transmits the search keyword input in step S32 to the search site (step S32), and acquires the search result (step S33).

  Next, the information processing device 1 extracts a history keyword from the program viewing history information included in the operation history information of the television device 2 (step S34). For example, the history keyword may be described most frequently in content description data associated with content that the user has recently viewed.

  In step S35, the information processing apparatus 1 narrows down the search results acquired from the search site using the history keyword extracted in step S34. The narrowed result is displayed on the display (step S36).

  In this way, the information processing apparatus 1 further narrows down the search results from the search site using the program viewing history information of the television device 2, so that the user's history information can be transmitted to the search site without sending it to the user. Search that reflects the taste of the user.

  FIG. 13 shows a display example when an application is installed. Normally, as shown in FIG. 13A, a screen that allows selection of “standard installation” and “all installation” as an installation method is displayed.

  Here, for example, when the information processing apparatus 1 acquires the program viewing history information of the television apparatus 2 and obtains information that the user has a lot of computer-related program viewing as the preference information, or the television apparatus 2 receives the information. When device information or operation history information is acquired from the processing device 1 and preference information indicating that the information processing device 1 is frequently used is obtained, as shown in FIG. “Standard installation”, “custom installation”, and “all installation” may be selected. In other words, the user's operability can be improved by reflecting that the user is interested in computer relations and presenting many installation methods.

  In the above embodiment, the device information and the operation history information are directly acquired from the electronic device having the information. However, as shown in FIG. 14, the server 5 that stores the device information and the operation history information. You may get through.

  The server 5 has storage means for storing device information and operation history information from the information processing apparatus 1 or the television apparatus 2 together with personal identification information. Then, in response to the request for the device information and the operation history information, the information having the same personal identification information is transmitted.

  The server 5 is preferably connected to a LAN (Local Area Network), for example, and preferably transmits / receives device information and operation history information only by devices in the network. Thereby, for example, device information and operation history information can be shared only by specific people such as the same person or family.

  In the above-described embodiment, the information processing apparatus 1 and the television apparatus 2 are described as an example of an electronic device that constitutes the operation control system.
